OSX 10.11.2 multiple monitors mixed retina and non-retina
-
macOS
Description
When multiple monitors present and one of them is retina and second is non retina:
What I expect
When I move application between displays icons change accordingly
What I have
On retina it looks ok, but when I move to non-retina display, icons looks terribly, because it only downscale from retina icons
Code works fine, when only one monitor is present. On retina it chooses high dpi icons on non-retina low dpi icons. Problem is only mixed multiple monitors.
#include <QtGui> #include <QtWidgets> int main(int argc, char *argv[]) { QApplication a(argc, argv); a.setAttribute(Qt::AA_UseHighDpiPixmaps, true); QTreeView treeView; QFileSystemModel model; treeView.setModel(&model); QModelIndex index = model.setRootPath("/"); treeView.setRootIndex(index); treeView.show(); return a.exec(); } #include "main.moc"
I also have tried to change it manually, but devicePixelRatio always gave me bad result. Maybe not prepared for mixed screens.
I expected
devicePixelRatio 2 for retina screen
and 1 for non retina screen
I got
Always 2 for all displays when retina monitor was present
void Window::moveEvent(QMoveEvent *event)
{
int number = QApplication::desktop()->screenNumber(this);
auto screen = QApplication::desktop()->screen(number);
qDebug() << screen->devicePixelRatio();
qDebug() << "screen number: " << number;
qDebug() << "screen->devicePixelRatio();" << screen->devicePixelRatio();
qDebug() << "screen->logicalDpiY();" << screen->logicalDpiY();
}
